Base Knowledge
There is no recommended background knowledge.
Teaching Methodologies
Lecture by the teacher of contents related to the theoretical aspects of this curricular unit, as well as interactive theoretical-practical classes that aim not only to transmit knowledge, but also to understand, interpret and apply them in concrete situations.
Learning Results
At the end of this course the student should be able to:
• Acquire the theoretical foundations of sample preparation, preparation and standardization of solutions and sample treatment for chemical analysis
• Analyze calibration curves and establish their application limits
• Determine the precision and accuracy of analytical results and critically interpret them.
Program
1. The Analytical Process. Sampling. Sample preparation. Principles of analytical measurement.
2. Statistical evaluation of analytical results. Accuracy and precision of analytical observations and measurements. Sensitivity, selectivity and specificity concept. Systematic and random errors. Uncertainty concept. Quality control statistical tests.
3. Calibration in Analytical Chemistry. General basics of calibration. Regression and calibration. Errors in linear calibration. Statistical tests and calibration validation. Alternative procedures to calibration.
4. Presentation, interpretation and validation of analytical results. Presentation of analytical results. Interpretation of analytical results. Display of results close to the detection limit. Interlaboratory studies. Chemometric interpretation of analytical data.
